When you say "intake", what are you talking about? Are you asking for an *intake manifold?* If so, Dinan makes one, but it might cost more than your car is worth:Originally Posted by ILoveMPower

If you're talking about improving air flow, maybe there's a reason why nobody has made a "bolt-in cold air intake." IT DOESN'T MAKE A DIFFERENCE!!!
Do you think some after-market company, even one with resources like Dinan haven't considered it? One thing to consider, BMW spends millions tuning their cars.
The key here is COLD air flow. The stock system does this very well. IF you really think you need something "extra," put in a K&N filter. You'll spend $50 and feel better....
